The soft pedal or una corda pedal (Italian for 'one string'), is one of the standard pedals on a piano, generally placed leftmost among the pedals. On a grand piano this pedal shifts the whole action (including the keyboard) slightly to the right, so that the hammers which normally strike all three of the strings for a note strike only two of them. This softens the note and also modifies its tone quality. Tone quality is also affected by forcing the remaining two strings being struck to make contact with a part of the hammer felt which is not often hit (due to the whole action being shifted); this results in a duller sound, as opposed to the bright sound which is usually produced (due to the felt being hardened from regular use).
